To all whom it may conc'em:

Be it known that I, Bonner G. STEWART, a citizen of the United States, residing at No. 166 Montgomery street, in the city of 'Newburgh, county of Orange, and State of New York, have invented a new and useful Composition of Matter to be Used for Bemoving- Dried Paint, Varnish, and Lao, of which the following is a specification.

My composition consists of a suitable ether, anilin, and an ingredient such as paraflin oil for retardin evaporation. It has been found that exce lent results can betobtained with a composition formed of 200 parts acetic ether, 30 parts anilin, and 1 part paraffin oil.

The ethers referred to would embrace sulfuric' ether, ethyl acetate, ethyl-butyrate, am 1 acetate, ainyl 'butyrate, ethyl va erate and ainyl valerate. The property required of'the evaporation retarder such as the paraflin oil referred to is that it should be soluble in the ether and anilin to a slight extent only.

In this com osition the. ether acts directly upon the dried or oxidized oil in the paints and the dried ums and lacs in the varnish and dissolves t em; as the ether evaporates it leaves -deposited 1n the dissolved and softtened oils or giuns or lacs the a-nilin, which iss'olution commenced byt-he ether and, being a less volatile substance than the ether, keeps the oils, gums or lacs 111 a softened condition; the paraflin retards the evaporation of the other upon its uppli cation. While the ether alone with'the pal-'- aflin oil will form a point and varnish solvent, yet the addition of the heavier solvent, anilin, not only increases the activity of the composition as a solvent hut greatly prolongs and continues its effect.

The ingredients are to be thoroughly mingled by agitation.

I claim:

'1. A composition for rcn'ioving dried paints, varnish or lac, the said composition comprising a mixture of other, anilin for prolonging the activity of the other, and

arafiin oil for retarding the evaporation of the ether when the composition is first applied. 3

2. The herein described composition for reinovii'ig dried paints, varnish or hit, the said composition comprising a mixture of 200 parts acetic ether, 30 ports anilin, and 1 part poraiiin oil.
